    Re: Where on block does negative cable connect? On my 1988 125HP motor, the negative cable is attached to a bolt on the side of the block close to the starter solenoid. Right where my finger is pointing. The copper clamp in the picture is on the head of the bolt that attaches the neg. cable...

    120 Force Outboard carburetor question(s)

    Re: 120 Force Outboard carburetor question(s) If the plastic screws are what I'm thinking they are, those are actually screw in plugs that seal off the idle air jet passages. They should not be loosened up at all. If you remove them and look closely into the passage, you'll see a small brass...

    Fuel leaking out side of carb

    Re: Fuel leaking out side of carb Just for clarification. The idle screw you mentioned in post #7. Are you referring to the screw on the carburetor? or the screw on the tower shaft. The screw on the carburetor is the idle mixture screw. It should be set to 1 to 1 1/2 turns out from lightly...

    Fuel leaking out side of carb

    Re: Fuel leaking out side of carb Are you sure it's a screw? Each carburetor has a brass fuel bowl vent insert that has a metered hole in it. If gas is leaking out of the fuel bowl vent (see circle in picture below), it's because there is too much gas in the fuel bowl due to: 1. Needle...

    Down under rebuild of 90HP Force

    Re: Down under rebuild of 90HP Force The puller shown in the video is actually a low cost Chinese import sold by a company here in the U.S. called Harbor Freight. If you do replace the bearing, use some loctite on it to help prevent it from moving on the crankshaft as a precaution. This...

    Force 120 hp Alternator Amp Output

    Re: Force 120 hp Alternator Amp Output I know that automotive starters can pull in the neighbor hood of about 200 - 250 amps max. A lot of the battery cables I see are 6 gauge. Using that as a general guideline and the chart below, I would venture to say that 4 gauge will probably work fine...

    84 85hp force no spark on 1 and 3

    Re: 84 85hp force no spark on 1 and 3 Yes it should work. All of the major components should swap right over. Just be prepared for some small gotcha's. It's hard to predict what you might run into when doing a swap like that. I went one step further on my 1988 125HP motor. Replaced the...

    Tools for Static timing.

    Re: Tools for Static timing. Yes, just use a remote starter switch connected directly to the starter solenoid. This is what I use for static timing. Just another variation on what Jerry uses. Remote starter switch. I usually do this by myself, so the remote switch makes it very easy...

    89 Force 50 HP will not turn off with switch nor kill switch

    Re: 89 Force 50 HP will not turn off with switch nor kill switch In order to stop the motor, the ignition signal is "grounded" when you turn the key to the Off position. Pushing the key to engaged the choke simply floods the motor. Not the best way to stop your motor. Looking at the third...

    My first boat and motor - 1993 Force 120 No spark from any spark plug

    Re: My first boat and motor - 1993 Force 120 No spark from any spark plug The Kill Switch grounds the ignition signal. To disable it, you just disconnect the wires. The Kill Switch is wired directly to the ignition switch. Usually a white wire (or black/yellow) on the first "M" terminal on...

    Re: 90hp Fuel pouring out of Carbs. Question. When you adjust the floats, are you turning the carburetor upside down and bending the tang that pushes against the needle valve so that the float is resting parallel to the carburetor body? Sometimes you have to adjust the float so that the...

    90 hp 1993 force water problem

    Re: 90 hp 1993 force water problem I'm pretty sure you have to take the power head off to replace the rubber grommet on the end of the water tube. I would inspect the water pump impeller to make sure it's intact. Might be a piece of rubber impeller that stuck in the water passage. Having...

    50 hp force no spark...

    Re: 50 hp force no spark... You should have 3 small threaded bolt holes around the nut on top of the flywheel. You need one of these tools. Once you attach it to the flywheel, crank down on the large center bolt. Take a steel hammer and whack the large center bolt like you're trying to...

    50 hp force no spark...

    Re: 50 hp force no spark... Sounds like my diagram doesn't exactly match your color codes. Not unusual. Anyways, there are two terminal strips. One has 8 positions, the other has 6 positions. I believe the terminal strips are located on opposite sides of the motor from each other. The...

    Tilt / Trim Force 50hp - Slow Leak

    Re: Tilt / Trim Force 50hp - Slow Leak You're almost there. Attached is a further breakdown of the check valves. There is a very small O ring inside. If it is leaking, your motor won't stay up. You have to pry off the cap of the check valve to get to the O ring inside. If you notice...

    Sierra filter install 97 120 force

    Re: Sierra filter install 97 120 force This is how it should look. The mount has more ports than you need, so you have to plug two of them up with 1/4" pipe plugs. I'm pretty sure they're 1/4" pipe plugs. Note the arrows. Line on the right comes from the fuel tank. Line on the left goes...

    Re: force piston position in cylinder Yes, the curved baffle on the top of the piston should point towards the intake ports. Here's a picture of a 4 cylinder, but it's the same as your 3 cylinder.

    Spark plug difference

    Re: Spark plug difference As Jiggz stated, the NGK BUHX is s boost gap plug. There is an internal gap inside the spark plug. If you take an OHM meter and measure between the center electrode to the metal tip that the wire attaches to, it will read "Open". No continuity. This type of plug...

    guages install

    Re: guages install From what I can remember, if your motor is a 1994, most likely it has the blue CD ignition modules. If you have the 2 blue CD modules like in the picture, then you have a 20 pole stator. You need a tach that is compatible with a 20 pole stator. If your tach is not...
